| Abstract | Network coding has emerged as a promising approach for peer-to-peer converged ubiquitous networks to increase network capacity and solve the block reconciliation problem. However, peer-to-peer systems with network coding suffer a severe security threat, known as pollution attack, in which malicious peers inject corrupted packets into the information flow. Previous solutions are either computationally expensive or too ineffective to limit pollution attacks with arbitrary collusion among malicious peers. In this paper, we propose time keys, an efficient security scheme which allows participating peers to efficiently detect corrupted packets by using time and space properties of network coding. Our work is an innovative security solution to frustrate pollution attacks with collusion based on time and space properties of network coding. In addition, time keys scheme provides an efficient packet verification without requiring the existence of any extra secure channels. We also present security analysis and simulations of our scheme, and results demonstrate the practicality and efficiency of time keys scheme. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
